- OMC Cobra 1.41 final drive ratio. 5.7 rebuilt to 300 hp 11/ 08. Hustler 15. x 15 prop. reman quadraj
These readings are taken with the boat running on the muffs at about 1200 rpm. The system is an omc 210 from san juan engineering and is a full system with coolant running through the manifolds. The engine has less than 1 hour on it from making adjustments, timing etc and getting baise line readings. Engine is a 350 chevy that is carberated and is OMC. The port side manifold runs about 30 degrees hotter than the starboard, the manifolds were not changed durring the rebuild. The port side manifold looked new, I thought if I was going to have a problem it would be on the starboard side. The port runs about 217 and the starboard runs about 185-190. I already have 2 new manifolds comming, if I do one I might as well do the other and start off with 2 new ones. does anyone have any Ideas what could cause this differance or has anyone else ever had this problem and how was it solved. Is it a problem? Am I on the right track? Thanks in advance
